Description

Ruminal protozoa decrease the bioavailability of copper in sheep receiving soybean meal (SBM) but not in sheep receiving casein (CA) as a protein supplement. Protozoa ingest SBM and release inorganic sulfur and amino acids. The sulfur is reduced by bacteria in the rumen to sulfide, which forms insoluble complexes with copper and so lessens the bioavailability of this element. CA, however, is poorly metabolized by protozoa, and so protozoa have no effect on the dietary copper metabolism when sheep are fed CA supplements. 5 refs, 1 tab
